PHP how to combine multiple if-statements into one function - php

Question

Based on a checkbox value this form will add subscribers to a corresponding list, but it can't save more than one value.
How do you merge, in order, to select and save more than one checkbox value?
if(isset($_POST['checkbox_list']) && in_array('Austin Metro', $_POST['checkbox_list'])){
$listID = '3';
if ($listID){
$indeed_mail->indeed_wysija_subscribe( $listID, $email );
}
break;
} else if(isset($_POST['checkbox_list']) && in_array('Central Austin', $_POST['checkbox_list'])){
$listID = '4';
if ($listID){
$indeed_mail->indeed_wysija_subscribe( $listID, $email );
}
break;
} else if(isset($_POST['checkbox_list']) && in_array('Georgetown', $_POST['checkbox_list'])){
$listID = '5';
if ($listID){
$indeed_mail->indeed_wysija_subscribe( $listID, $email );
}
break;
}

This might be what you're looking for... ?
$myValues = array('Austin Metro','Central Austin','Georgetown');
$myIds = array('3','4','5');
if (isset($_POST['checkbox_list']) && array_search($_POST['checkbox_list'], $myValues) !== false)
{
$index = array_search($_POST['checkbox_list'], $myValues);
$indeed_mail->indeed_wysija_subscribe( $myIds[$index], $email );
}
EDIT : I just read your comment above...
To grab your checkboxes as an array use :
<input type="checkbox" name="checkbox_list[]" value="Austin Metro">
<input type="checkbox" name="checkbox_list[]" value="Central Austin">
<input type="checkbox" name="checkbox_list[]" value="Georgetown">
Then
foreach($_POST['checkbox_list'] as $check)
{
// do your stuff as explained above...
if (isset(check) && array_search($check, $myValues) !== false)
{
$index = array_search($check, $myValues);
$indeed_mail->indeed_wysija_subscribe( $myIds[$index], $email );
}
}
